Question Faulty GTX 780 ti. blackscreen and purple lines

Jun 21, 2019
My GTX 780 Ti recently stopped working properly, when I turned on my pc it loaded up the bios screen then when I tried to launch windows all I get is a black screen. So I took out the card and booted up with my onboard graphics and everything worked fine. After that, I used DDU to completely uninstall all the graphics drivers on my system, put in the card again and it loaded up perfectly. When I went to install the drivers again my screen was filled with around 100 small horizontal purple lines that popped up and disappeared throughout the install. Once the install was done my pc restarted and returned to the starting point. Fan spins and LEDs work.
Any help on how to fix this issue would be greatly appreciated, I do have a heat gun if a reflow is needed.
